PUMP.

Specification of Letters Patent.

Patentcal May 25, 1920.

Application filed December 23, 1919. Serial No. 346,930.

To u?! vi mm 1' 2* may concern:

Be it known that I, ARTHUR Pmnov, of the town of \Vapclla, II] theProvince of Saskatchewan, (hnada, have invented certain new and usefulimprovements in lumps, of whichv the following; is the specitieati-on.

The invention relates to improvements in ordinary reciprocating handleentirely dispensed with and a hand wheel. provided "which when properlymanipulated with other parts does the required work.

further object of the invention is to mustruct the pump in a simple.inexpensive and. durable manner and such that it can be readilyinstalled and can be relied upon to eil'wtiwly do its work.

With the above general objects in view the invention consistsessentially in the arraugmnent and construction of parts hereinaftermore particularly described and later pointed out in the appendedclaims, reference being: had to the accompanying drawin n in which ligure 1 is a. vertical sectional View through a well showing myinvention installed.

Fin. 2 is a horizontal sectional view at E2-2 Fin. 1 and lookingdownwardly.

Fig.3. ii is a horizontal. sectional view throughv the well at 3--3 Fig.1.

M i. is an enlarged 'ertical sectional view through. the valve.

Tn the drawing); like characters of reference indicate corres 'iondinc:parts in the several. figures.

1 represents the well which is suitably lined by boards 2 or similarfacing pieces preventing! the dirt from falling in. The top of the wellis closed by a platform 3 and at the bottom of the well I locate acentrally dis 'iosed vertically extending cylin der 4 having the upperend open and the bottom end closed as shown at The cylinder is held in afixed position in the bottom of the well by suitably disposed fasteningbrackets 6 attached to the cylinder and the well lining.

l is a plunger mounted for reciprocating movement within the cylinderand 8 is a valve attached to the lower end of the cylinder and arrangedto permit of the passage of water inwardly to the cylinder and to closeupon a back pressure being developed in the cylinder by the down movement of the piston. The details of this valve are not herein enlargedupon, it being simply a flap valve as clearly shown in Fig. 41.

The plunger is carried by a vertically extending centrally positionedhollow pipe or tube 9 exteluling upwardly toward the top of the well.and connected by a T-pipe 10 to the lower end of a; jack screwll and toa discharge pipe 12 more or less of anL-shape. The jack screw and thedischarge pipe pass freely through the platform and at the upper end ofthe ack screw I locate a box 13 loaded with stones or similar weights14. .i tap 15 is provided at the upper end of thedischargc pipe and ifdesired. a flexible hose 16 can be attacl'ied to allow of the directingof the water discharged. The pipe 9 is suitably guided for slidingmovement in a bearing 17 carried by brackets 18 similar to those shownat 6. 19 is a head plate car ried by suitable legs 20 bolted. to theplatform. The jack screw passes freely through the head plate and thehead plate is utilized as a working bearing for a comparatively largehand wheel '21 opcratively mounted on the jack screw and provided with ac01npara-tively heavy rim.

When one desi res to pump water with this a ppliance he closes the tap15 and turns the hand wheel in one direction. say a clockwise direction,which. action iaus'es the jack screw to rise against the action of theweight 14 and in rising it pulls up the plunger and draws water into thecylinder through the valve 8. 1

(lliiviously as the jack screw and pipe 9 go up the discharge pipe goesupand for this reason it is dcsiraliile to have a flexible connectionsuch as a hose 1.6 to control the water when later discharred.

When one is ready to discharge the water he opens the valve and. thengives the hand wheel a quick turn in the reverse direction or acounter-clockwise direction and if the wheel is pulled quickly it will.spin up the jack screw away from the plate 19, the upward movement ofthe hand wheel being quicker than the down movement of the jack screwacting under the action of the weight 14.

Obviously as soon as there is a clearance between the hand wheel and thehead plate the weight acts to force the plunger down with the resultthat the valve 8 closes and the water is discharged up the pipes 9 and12 and out the hose, provided of course the tap is opened. If however,the tap is not opened the water trapped in the cylinder will hold theweight in the box so that one can draw water any time he opens the tapprovided the weight box is up and the hand wheel is away from the headplate.

From the above it will be apparent that this provides a very easyarrangement for pumping water as it requires little effort on the partof the operator, the pumping being actually done by the weight and allthe operator has to do is to first turn the hand wheel in one directionand then give it a quick turn in the other.

By providing a heavy rim to the hand wheel it acts in the nature of afly wheel and will spin up from the plate if it is given a good pull tostart with.

What I claim as my invention is 1. In a well, a stationary cylinderlocated in the base of the well, a normally closed intake valveconnected to the lower end of the cylinder, :1. piston operativelymounted within the cylinder, a hollow main pipe connected to thecylinder and extending upwardly within the well, an offset dischargepipe connected to the former pipe, a valve controlling discharge throughthe discharge pipe, a weighted jack screw connected to the main pipe, astationary head plate surrounding the jack screw and operating meansscrew threading on to the jack screw and normally bearing on the headplate and designed when turned in one direction to raise the jack screwand parts connected thereto.

2. In a well, a stationary cylinder located in the base of the well, anormally closed intake valve connected to the lower end of the cylinder,a piston operatively mounted within the cylinder, a hollow main pipeconnected to the cylinder and extending upwardly within the well, anoffset discharge pipe connected to the former pipe, a valve controllingdischarge through the discharge pipe, a weighted jack screw connected tothe main pipe, a stationary head plate surrounding the jack screw and ahand wheel mounted on the jack screw above the head plate.

3. In a well, a stationary cylinder located in the base of the well, anormally closed intake valve connected to the lower end ol' thecylinder, a piston operatively mounted within the cylinder, a hollowmain pipe connected to the cylinder and extending upwardly within thewell, an offset discharge pipe connected to the former pipe, a valvecontrolling discharge through the discharge pipe, a weighted ack screwconnected to the main pipe, a stationary head plate surrounding the jackscrew and an operating hand wheel operatively mounted on the jack screwabove the head plate and provided with av comparatively heavy rim.

4;. In a well, a stationary cylinder located in the base of the well, anormally closed intake valve connected to the lower end of the cylinder,a piston operatively mounted within the cylinder, a hollow main pipe connected to the cylinder and extending upwardly within the well, an offsetdischarge pipe connected to the former pipe, a valve controllingdischarge through the discharge pipe, a vertically extending jack screwextending out of the well and having the lower end permanently connectedto the upper end of the main pipe, a comparatively heavy weight locatedat the upper end oi the jack screw, a permanently supported hearingplate surrounding the ack screw and an operat-ing hand wheel operativelymounted on a jack screw in a location above the plate.

5. In a well, acylinder permanently fixed in the bottom of the well andhaving a closed lower end, a normally closed inlet valve located at thebottom of the cylinder, a piston operatively mounted forreciprocatingmovement within the cylinder, a main vertically extendingwater pipe carrying the plunger and opening to the interior of thecylinder through the plunger, an offset discharge pipe communicatingwith the upper end of the main pipe and extending out of the well, avalve controlling discharge from the upper end of the discharge pipe, ajack screw vertically alined with the main pipe and permanentlyconnected thereto and extending upwardly out of the well, a weight boxmounted on the upper end of the jack screw, a permanently supportedbearing plate surrounding the jack screw outside the well and a handwheel operatively mounted on the ack screw above the bearing plate.
